Application filed July 28,1921. Serial No. 488,114.

To all whom it may concern:

Be it known that we, ANTONIO J. CAsALE and JOSEPH B. SIMPSON, citizensof the United States, residing at Takoma Park, in the District ofColumbia and city of Washington, have invented certain new and usefulImprovements in. Automobile Brakes, of which the following is aspecification.

'Our invention relates to improvements in automobile brakes, one objectof the invention being the provision of a brake drum construction for aninternal brake in which certain portion of the brake band receiving rimsare so constructed as to be adjustable and thus provide anexceedingly'simple, inexpensive and durable arrangement to increase orlengthen the life of the brake drum.

This brake drum is especially designed for use in motor cars and insteadof proyiding a drum with a fixed annular rim, the rim is made with twoor more portions thereof resiliently attached to the body of the disk ordrum with spring actuated adjusting means for adjusting the size of thedrum for cooperation with the internal brake mechanism.

In the accompanying drawings:

Figure 1 is a section taken on line 11 of 1 Figure 2.

Figure 2 is an lnternal plan view of the complete brake drum andinternal brake.

Figure 3 is a reduced View with the inter nal brake removed.

Figure 4 is a view similar to figure 2 of a modified form.

Figure 5 is a view in top plan thereof with a portion of the wheel beingshown.

Referring to the drawings, and more particularly to Figures 1, 2 and 3,thereof, the wheel 6 has attached thereto in the usual manner, the drum7 which in this construction is provided with the rigid portion 8 of therim whose two oppositely disposed spring band portions 9 are providedwith apertured ofisets 10 and 11 for the reception of the adjusting bolt12, the two springs 13 being so disposed between the fixed guidingapertured lug 14 and the two terminals 10 and 11 as to hold the thumbnut 15 in adjusted position with the cooperating projection 16 and therecess 17.

From the foregoing it will be seen that by adjusting the flexiblemembers 9 toward each other, any wear can be taken care of upon theinner surface of the brake drum to compensate for the wear upon theouter surface of the internal brake members 18 which are of the usualconstruction employed upon motor cars.

I In the construction shown in Figuresi and 5, the drum 7 is providedwith the rigid portions 8 at diametrically opposite points of the rimand with four flexible or spring band partial members 9, whichcorrespond to and are made similar to the members 9 heretoforedescribed, the other parts of the device being exactly the same. In thisform, two adjusting points are provided for the band relative to the twointernal brake members 18. s

From the foregoing description, it is evi dent with a construction ofthis type that the life of the emergency brake is greatly 111- creasedand any wear upon the respective braking members can be taken care ofreadily without removing the internal member but by merely adjusting thevarious thumb nuts 15 and 15'. v 1

What we claim as new is:

1. A brake drum having its rim rovided with an adjustable springtensions braking member, a bolt for adjusting the member to increase ordecrease the tension thereof, and springs carried by the bolt forimparting a resilient tension at the adjusting point ofisaid brakingmember.

2. An emergency brake including a disk having a rim attached thereto atone point with two oppositely extending spring tensioned contiguousportions, the ends of which are apertured and ofi-set, and means foradjusting the ends relative to each other.

3. An emergency brake including a disk having a rim attached thereto atone point with two oppositely extending spring tensioned contiguousportions, the ends of which are apertured and ofi-set, and springexpanded means for adjusting the ends relative to each other.

In testimony whereof we-afiix our signatures. v
